More broadly enforce Allman style and braces-around-conditionals

We want { and } aligned, which means also adding a newline between each
for() and {, while() and {, etc.

Also, we agreed to always use braces with conditionals.  The previous
uncrustify config added these for if()s, now also add these for while()
and for().
